It's changeuuid.py in https://github.com/mndar/rbf/tree/master/commonscripts It doesn't depend on anything else in the repo, so you can just download that script. Sample Usage: # just show what is going to change ./changeuuid.py pretend /dev/sdb /tmp/temp/ # actually change ./changeuuid.py change /dev/sdb /tmp/temp/ Refer the README for more details. Let me know if you have any issues. -Mandar Joshi
